Dot, an Australian girl, seeks the magical green root that will give her the ability to talk to animals. She eats a red root by mistake, and is shrunk to the size of an ant. With the help of her friends Keeto the mosquito and Butterwalk the caterpillar, she searches for the green root that will restore her size. But she must find it before sundown, or she will shrink even smaller.

After months of being alone, sad, busy, sidetracked, free, lofty, late and away from his kids, Lenny, 34 with graying frazzled hair, picks his kids up from school. Every year he spends a couple of weeks with his sons Sage, 9, and Frey, 7. Lenny juggles his kids and everything else all within a midtown studio apartment in New York City. He ultimately faces the choice of being their father or their friend all with the idea that these two weeks must last 6 months. In these two weeks, a trip upstate, visitors from strange lands, a mother, a girlfriend, "magic" blankets, and complete lawlessness seem to take over their lives. The film is a swan song to excuses and responsibilities; to fatherhood and self-created experiences, and to what it's like to be truly torn between being a child and being an adult.

What is a mosquito's nature? A large man enters his flat; a mosquito in top hat with valise follows, entering through the window above door. The man goes to sleep; the mosquito lands next to him, opens the valise, and takes out a grinding wheel to sharpen his proboscis. Methodically, the mosquito gets one, two, then three drinks as the man tosses, slaps, turns, covers himself, and rubs the wounds. After a fourth drink, the mosquito is so full he can barely right himself. Still he has more. Bloated, he can only hover above the sleeping man's face. Suspense builds: can he launch? He's atop his victim's nose. He jettisons his valise. Will he now be light enough to escape?

Then, Chitti falls in love with Dr. Vasi's fiancée Sana (Aishwarya Rai) and turns on his creator.
